Cold Melt® Liquid Applied Membrane - Liquid-Applied Roof Waterproofing

Pro-Prime® SA.

Guidance for specification option:

For Concrete/ Timber Deck.

• For best results ensure that surfaces to be primed are free from oil or dust.
• Apply Pro-Prime® SA by roller or brush at a rate min of 5 m²/lit (the green colour will indicate the treated area); refill roller if ‘cobwebbing’ appears. Avoid puddling of the primer.
• Drying time will be affected by surface porosity, film thickness and temperature and can vary between 40-90 minutes.
• Pro-Prime® SA will remain tacky even after dry.
• To test, use the back of a glove or dry object to press into the primer and remove; there should be no transfer of primer when the primer is ready. It is essential that sufficient drying time is allowed as any entrapment of solvent will result in blistering/ delamination.
• Only prime areas that will be covered with Pro-Carrier SA within 2-3 hours. Avoid walking over areas already primed.

Cold Melt® DPM.

Guidance for specification option:

For green concrete.

• Only to be used after consultation with Proteus technical team.

Pro-Epoxy Primer.

Guidance for specification option:

For Metal Substrates.

• Apply Pro-Epoxy Primer to all areas to be waterproofed at a minimum rate of 0.17 L/m².
• Ensure that the primer is fully cured prior to the waterproofing system being applied.
